If ris rational (r6= 0) and xis irrational, prove that r+ xand rxare irrational. Prove that there exists a real continuous function on the real line which is nowhere differentiable. (a) Show that √ 3 is irrational. 2. The Riemann Integral and the Mean Value Theorem for Integrals 4 6. In real analysis we need to deal with possibly wild functions on R and fairly general subsets of R, and as a result a rm ground-ing in basic set theory is helpful. Math 4317 : Real Analysis I Mid-Term Exam 2 1 November 2012 Name: Instructions: Answer all of the problems. De nitions (1 point each) 1.For a sequence of real numbers fs ng, state the de nition of limsups n and liminf s n. Solution: Let u N = supfs n: n>Ngand l N = inffs n: n>Ng. Improper Integrals 5 7. Partial Solutions: 1. But analysis later developed conceptual (non-numerical) paradigms, and it became useful to specify the diﬀerent areas by names. Assume the contrary, that r+xand rxare rational. very common in real analysis, since manipulations with set identities is often not suitable when the sets are complicated. Derivatives and the Mean Value Theorem 3 4. We get the relation p2 = 3q2 from which we infer that p2 is divisible by 3. Real Analysis Math 131AH Rudin, Chapter #1 Dominique Abdi 1.1. True. Limits and Continuity 2 3. Then limsup n!1 s n= lim N!1 u N and liminf n!1 s n= lim N!1 l N: (a) For all sequences of real numbers (sn) we have liminf sn ≤ limsupsn. The origins of the part of mathematics we now call analysis were all numerical, so for millennia the name “numerical analysis” would have been redundant. (10 marks) Proof. “numerical analysis” title in a later edition [171]. 3. Undergraduate Calculus 1 2. Define finite Show that m(p) is a O-ring Sample Assignment: Exercises 1, 3, 9, 14, 15, 20. Solution. If g(a) Æ0, then f/g is also continuous at a . We begin with the de nition of the real numbers. Students are often not familiar with the notions of functions that are injective (=one-one) or surjective (=onto). Since the rational numbers form a eld, axiom (A5) guarantees the existence of a rational number rso that, by axioms (A4) and (A3), we have True or false (3 points each). to Real Analysis: Final Exam: Solutions Stephen G. Simpson Friday, May 8, 2009 1. SAMPLE QUESTIONS FOR PRELIMINARY REAL ANALYSIS EXAM VERSION 2.0 Contents 1. FINAL EXAMINATION SOLUTIONS, MAS311 REAL ANALYSIS I QUESTION 1. The axiomatic approach. (b) Every bounded sequence of real numbers has at least one subsequen-tial limit. The real numbers. Questions (64) Publications (120,340) ... (PDF). True. Retrieved 2011-07-23. THe number is the greatest lower bound for a set Eif is a lower bound, i.e. Math 312, Intro. If the real valued functions f and g are continuous at a Å R , then so are f+g, f - g and fg. x for all x2Eand if 0 is any other lower bound for the set Ethen we have that 0 . Suppose that √ 3 is rational and √ 3 = p/q with integers p and q not both divisible by 3. QN T.Y.B.Sc. If f and g are real valued functions, if f is continuous at a, and if g continuous at f(a), then g ° f is continuous at a . (7) Explore the latest questions and answers in Real Analysis, and find Real Analysis experts. 7. There are at least 4 di erent reasonable approaches. REAL ANALSIS II K2 QUESTIONS : Unit 1 1. Hence p itself is divisible by 3, as 3 is a prime PAPER II– REAL ANALYSIS Answer any THREE questions All questions carry equal marks. 3.State the de nition of the greatest lower bound of a set of real numbers.
